It uses the pressure of the atmosphere on a metal box to deform the box, and drives the pointer through a lever system so that the pointer indicates the value of the air pressure at that time on the dial. Generally, it is only used as a reference instrument at stations and is mostly used for field observations. It has the advantages of easy portability, accurate measurement, wide pressure measurement range, easy use and maintenance, and no mercury pollution. It is widely used in meteorology, military, aviation, navigation, agriculture, surveying, geology, industrial and mining enterprises, and scientific research. It is a conventional instrument for measuring atmospheric pressure. An instrument casing is usually installed on the outside of the barometer to provide protection for it.

[0003] The existing air pressure instrument housing is generally two circular box bodies, which are installed using multiple locking bolts through threaded connections. As a result, when performing internal maintenance work on the air pressure instrument, the locking bolts need to be removed one by one using a screwdriver, which is time-consuming and labor-intensive.
